Automotive Direction Indicator
The IL33193 is a new generation industry standard UAA1041 “Flasher”.
It has been developed for enhanced EMI sensitivity, system reliability, and
improved wiring simplification. The IL33193 is pin compatible with the
UAA1041 and UAA1041B in the standard application configuration as shown
in Figure 9, without lamp short circuit detection and using a 20 mΩ shunt
resistor. The IL33193 has a standby mode of operation requiring very low
standby supply current and can be directly connected to the vehicle’s battery.
It includes an RF filter on the Fault detection pin (Pin 7) for EMI purposes.
Fault detection thresholds are reduced relative to those of the UAA1041,
allowing a lower shunt resistance value (20 mW) to be used.
• Pin Compatible with the UAA1041
• Defective Lamp Detection Threshold
• RF Filter for EMI Purposes
• Load Dump Protection
• Double Battery Capability for Jump Start
